>From kylem's RHEL8 post:
|
|
|
|
Let's not lose this ability in RHEL8. Sadly can't be applied to RHEL7
|
|
because it breaks KABI due to the struct module change.
|
|
|
|
Inspired by bits of a147e4729d9920ccae2c717ca65c811cc0f93a1d in RHEL6,
|
|
which got lost for RHEL7.0. :/
|
|
|
|
Kyle is correct and doing this would break RHEL7's KABI. I'm taking this
|
|
patch in as a base and the next patch will resolve the KABI issues.
|
|
|
|
[v2]: dzickus, cleanup add_rhelversion()
|
|
[v4]: resubmitted along with 16k stacks change
